Description

BACKGROUND

The present invention relates generally to a toy projective launcher assembly, and more particularly, but not by way of limitation, to an assembly that facilitates a discharges a soft foam toy projectiles, and includes an airfoil to propel the soft foam projectiles with minimal propulsion requirements.

Toys are often designed to have play value by simulating a real object but in a safe manner and at a reasonable expense. Guns and rifles have been marketed as toys for decades and include such devices as water pistols and rifles, cap guns, BB guns and rifles, dart guns and NERF™ brand launchers that discharge a soft foam toy dart.

Toy projectile launchers that eject toy projectiles with a burst of pressurized air are generally known in the art. For example, U.S. Pat. No. 5,724,954 to Smith discloses a projectile launcher having a housing, a projectile launch tube slidably joined to the housing for movement between a first position and a second position, a launch tube spring biasing the launch tube towards the first position and a piston slidably disposed in the housing for movement from an un-cocked position to a cocked position in response to the launch tube moving from the first position to the second position. The launch tube includes a first portion for releasably mounting a projectile and a hollow second portion in fluid communication with the first portion, with the piston moving from the cocked position to the un-cocked position to compress fluid in the second portion of the launch tube. The projectile launcher further includes a piston spring biasing the piston toward the un-cocked position, a sear slidably joined to the housing for releasably retaining the piston in the cocked position, and a release means for sliding the sear to release the piston from the cocked position.

There is a product on the market that has a larger hopper, but the weight makes it impractical for younger kids to wield. It also solves the problem of modularity.

However, such toy projectile launchers are low capacity and require frequent reloads. Also, the conventional toy projectile launchers are hand-held and are difficult to include a large storage device to have more projectile rounds each use without reload. Moreover, if a larger storage device for the projectiles is utilized, the assembly becomes larger and requires more power to project the foam projectiles.

Ride-ons are a category of children's toys that typically include a battery-powered, wheeled vehicle. The vehicle can include realistic, kid-sized features that allow a child to sit in or on the vehicle and control its speed and direction. Although many are designed as cars, ride-ons have expanded to cover battery-operated trucks, motorcycles, off-road vehicles, and different animals. As the design and operation of ride-ons evolve and expand, so does the need to provide adequate safety features to protect children as they play.

No one has considered the type of assembly to include a toy projectile launcher adapted to be configurable to use in a ride-on. When adapted to the ride-on, considerable more power is required than in a conventional toy projectile launcher in order to launch the projectiles from the ride-on.

SUMMARY

In view of the newly-identified problems in the art, the inventor has considered an improvement that includes an assembly device to provide a larger time between reload, adapt the toy projectile launchers to be included in a vehicle assembly (‘ride-on’), backpack assembly, or the like, and provide the needed power to for projecting the foam projectiles included a larger toy gun assembly in a simple, affordable assembly. Indeed, modifying a toy projectile launcher to a toy ride-on requires inventive steps and new problems not considered in the field of projectile launchers or ride-ons. That is, the inventive projectile launcher can be mounted on several configurations like a backpack style system or on a go-cart. It solves a problem of slow flowing projectile rounds found with a traditional hopper. This is accomplished by using forced air to assist in driving the projectiles through the feeder tube.

In an exemplary embodiment, the present invention provides a toy projectile launcher assembly installed in a ride-on vehicle having a flap, a tire as a storage device for projectiles, and a steering wheel with an activation switch, the toy projectile launcher assembly consists of a projectile launcher configured to project the projectiles, the projectile launcher having: a feeder tube, a flywheel, a barrel for projecting the projectiles, and spinning barrels disposed around the barrel, a hopper having a feeder carousel which feeds the projectiles via agitator arms from the tire into an air supply outlet of the hopper, and an air supply inlet having an airfoil that reduces a cross-sectional area of the air supply inlet at a portion nearest the feeder carousel to a first size from a second size located at an exit of the air supply inlet positioned farthest from the feeder carousel, a ball hose connecting the air supply outlet of the hopper to the feeder tube of the projectile launcher, the ball hose configured to carry the projectiles from the hopper to the projectile launcher, a blower that blows air into the air supply inlet of the hopper via a hose connecting the blower to the air supply inlet, wherein the flywheel accelerates the projectiles that are fed from the feeder tube to the flywheel at a first speed and out the barrel at a second speed that is faster than the first speed as a result of a rotation of the flywheel accelerating the projectile, wherein the blower provides air to the air supply inlet of the hopper which is sped up when passing the airfoil and entering into the hopper, and wherein each of the blower, the hopper, and the lift, and the projectile launcher include a separate electrical connection to the activation switch of the steering wheel.

By way of introduction of the toy projectile launcher assembly 100 depicted in FIG. 1, the invention includes a projectile launcher 200, a lift attached to the projectile launcher 200 a, a ball duct 300, a hopper 400, and a blower 500. FIGS. 2-9 depict detailed representations of the connections between each of the parts of the assembly 100.

It is noted that the toy projectile launcher assembly 100 is represented as part of a ride-on toy vehicle and will be described below according to this embodiment. However, the invention can be separated from the ride-on vehicle such as in FIG. 3 and adapted to be utilized in a different product for sale. For example, the lift 200 a can be removed and the projectile launcher 200 can be adapted into a more conventional looking toy projectile launcher (i.e., a toy gun) while the rest of the assembly is attached to a backpack with the hose 300 connecting between the backpack and the projectile launcher 200. In such an embodiment, the backpack would store the toy foam projectiles 800 a just as the tire 750 of the ride-on does in the below embodiments. The toy foam projectiles 800 a would be fed from the backpack into the hopper assembly and the blower would provide the activation for the toy foam projectiles to be shot from the projectile launcher. Once complete, it could be used as a stand-alone system on a tripod. It could also be easily used on any vehicle from a bicycle, tricycle, etc. to a Go Carts, Golf Carts, etc.

FIG. 2 exemplarily depicts a back-end of the ride-on vehicle. As is seen, the hopper 400 is installed to interface with the tire 750 (i.e., the storage device) for storing the toy foam projectiles 800 a. The blower 500 is installed in a bottom side of the vehicle and is electrically connected to the steering wheel 770 such that a user can activate the electricity via a switch on the steering wheel 770 to turn on the blower and provide power to the toy projectile launcher assembly 100. As power is supplied via the blower 500, the toy foam projectiles 800 a feed into the hopper (as described later) and are projected through the hose 300 to the projectile launcher 200 and shot therefrom as shown in FIG. 3.

Turning to FIGS. 3-9, FIG. 3 exemplarily depicts the toy projectile launcher assembly 100 separate from the ride-on vehicle. And, FIGS. 4-9 depict each element of the toy projectile launcher assembly 100 in more detail.

At a high-level, the invention propels the toy foam projectiles 800 a from the tire 750 via activation of the blower 500 (not shown in FIG. 3) through the hopper 400, the hose 300, and out the projectile launcher 200. The lift 200A is a design feature specific to integration with a ride-on toy. That is, a ride-on toy can be easily modified to include a “flap-type” assembly 760 on the hood of the ride-on which opens when the lift 200A is activated and the projectile launcher 200 is lifted up (as indicated by the arrows) and out of the ride-on hood such that the projectile launcher can launch the projectiles 800 a.

Thereby, the invention provides for a sleek, low cost, modification to an existing ride-on. Indeed, the ride-on with the toy projectile launcher assembly 100 is hidden while not being used. Therefore, the ride-on can be used completely without the assembly 100 being exposed from the hood and without even knowing the ride-on includes the assembly 100. At that, the assembly 100 can be sold as a kit to install in an already purchased ride-on or to a manufacturer of a ride-on to be sold therewith.

As noted above, the electrical controls of the ride-on device and the assembly 100 are located on a steering wheel 770. The lift 200A and the flap 760 on the hood are activated using a switch on steering wheel 770. Of course, the projective launcher 200 and flap 760 can be returned to a state back in the hood of the vehicle via a similar switch (or same switch) on the steering wheel 760.

With reference to FIGS. 4A-4D, the projectile launcher 200 is described and shown in detail.

FIG. 4A shows a section view of the projectile launcher 200. The projectile launcher includes an inspection port 215 that allows access to the interior of the projectile launcher. The inspection port 215 allows a user to check all electrical connections and/or check for a clog in the projectile launcher 200. The projectile launcher 200 includes a feeder tube 211 that connects with the ball duct 300 to feed the projectiles 800 a into the flywheel 214 assembly and project the projectiles 800 a through the barrel 212 of the spinning barrels 213. It is noted that the spinning barrel 213 is provided as an aesthetic upgrade to simulate a “machine-gun” but the barrel 212 is the only projectile dispersion barrel.

The flywheel 214 assembly includes two flywheels which are spun at a high speed via motors 216 a/b (i.e., motors that power a rotation of the flywheels). When the projectiles 800 a enter the feeder tube 211 prior to contacting the flywheels, the projectiles 800 a are moving at a first speed. When the flywheels 214 contact the projectiles 800 a, the speed is greatly increased and the projectiles 800 a are shot at a greater velocity than the first speed (i.e., at a second speed) out of the barrel 212.

The power supply 217 for the motors 216 a/b that power the flywheels 214 is activated as well by the steering wheel 770. As shown in FIG. 4B, a motor 216 c is included and connected to spin the barrel. Therefore, additional failsafe mechanisms and longer shelf life can be obtained by having multiple motors such that the projectiles 800 a can still be launched even if there is a malfunction with the spinning barrels 213. Independent electrical connections also make repair easier via the inspection port 215 as it is easy to identify the issue (i.e., flywheel 214 not spinning, spinning barrels not spinning, etc.).

FIG. 4C shows an example view through the inspection port 215 which shows a power supply 217 that can be accessed for repair. FIG. 4D shows how the wire for the power supply 217 can be fed out of the projectile launcher 200 and to the steering wheel 770.

FIGS. 5A-5D exemplarily depict the hopper 400, the feeder carousel 400A, and the airfoil 410. With reference back to FIG. 3, the hopper 400 is installed to interface with the storage device for the projectiles 800 a. In this embodiment, the storage device is the tire 750 on the back of the ride-on. The tire 750 is extremely large in comparison to the hopper 400 and even larger when compared to a conventional magazine clip for a toy gun or a storage of projectiles in a toy gun. That is, the tire 750 can include hundreds of projectiles 800 a whereas a conventional toy gun may only have between six to fifteen unless a larger storage device is provided but even with add-on packages bought from a manufacturer, the size of the storage is greatly limited since the conventional toy guns are hand-held.

But, because the storage device for the projectiles 800 a is a greater distance from the projectile launcher 200, greater power is required to push the projectiles from the storage to the projectile launcher 200 so that the flywheels 214 can accelerate the projectiles 800 a and launch them at a high velocity (i.e., second speed).

The hopper includes an air supply inlet 411 which receives the air blown from the blower 500 and an air supply outlet 412 which provides the air carrying the projectile out of the hopper through the ball duct 300 towards the projectile launcher 200 to be launched. The hopper 400 further includes a feeder carousel 400A attached to the hopper 400. The feeder carousel 400A includes agitator arms 414 which act to separate the projectiles 800 a as they are fed from the storage 770 into the hopper 400. The agitator arms 414 ensure that only one projectile 800 a exits through the air supply outlet 412 to the ball duct 300 at a time.

To facilitate the required “push” via blowing air from the blower 500 (as described later), an intuitive design of the hopper air supply inlet 411 is included herewith where an airfoil 410 is provided at an entrance from the air supply inlet to the hopper 400. The airfoil, as shown in FIG. 6A-6B, is designed based on Bernoulli's principle and the Venturi effect. In fluid dynamics, an incompressible fluids velocity must increase as it passes through a constriction in accord with the principle of mass continuity, while its static pressure must decrease in accord with the principle of conservation of mechanical energy (Bernoulli's principle). Thus, any gain in kinetic energy that a fluid may attain by its increased velocity through a constriction is balanced by a drop in pressure.

The air supply inlet 412 has the airfoil 410 that reduces a cross-sectional area of the air supply inlet at a portion nearest the feeder carousel 400A to a first size 480 from a second size 490 located at an exit of the air supply inlet positioned farthest from the feeder carousel.

The invention enables a blower of less power and less required airflow by utilizes an inventive placement of the airfoil 410 at the air supply inlet 411. The airfoil 410 reduces the cross-section of the air supply inlet 411 to increase the rate of the airflow. In one embodiment, the chord length is ¾ in. The camber line is ⅞ in. This gives the airfoil lower pressure on the side of the projectiles producing more speed with less relative wind from the blower. It follows the design principle of the hopper side of the airfoil 411 having a lower cross-section than that of the air supply inlet 411. Preferably, the cross-section is 75% the size. In a more preferable embodiment, the cross-section is 60% the size to even further increase the airflow.

In one embodiment, the angle of the airfoil 410 has an angle of 60°. The angle is measured from an entrance of the air supply inlet 411 into the hopper towards the wall of the air supply inlet 411 moving towards the exit such that the airfoil 410 slants down towards the hopper from an outer wall of the air supply inlet 411. In a more preferable embodiment, the airfoil 411 has an angle of 50°. FIG. 5A includes an axis for which the angle is measured from. Although angles have been given, it can be designed with an angle downward from the wall of the air supply inlet 411 such that the cross-section of the entrance to the hopper is reduced and accelerates the air flow into the hopper.

The hopper 400 includes a motor shaft opening 415 and motor attachment holes 416. As shown in FIGS. 7A-7B, a motor 450 is attached to the hopper 400 via the motor attachment holes 416 and the motor shaft 4501 protrudes from a face of the hopper 400 having the motor attachment holes 416. The motor shaft 4501 connects with the a feeder carousel 400A in such a manner to spin the feeder carousel 400A which accordingly spins the arms 414 causing the projectiles 800A to be fed into the ball duct 300. The motor 450 is powered by the power source 452 which is also connected to the steering wheel 770.

FIG. 9 exemplarily depicts a blower 500 which supplies air to the hopper 400 to push the projectiles 800 a to the projectile launcher 200. The blower 500 includes a blower motor 502 which also connects via a power supply 503 to the steering wheel 770 for activation. An air supply hose 501 is connected to an output of the blower 500 and provides air from the blower 500 in a direction 411A. The airflow direction 411A provides the airflow from the blower to the air supply inlet 411 of the hopper 400. The airflow provides into the air supply inlet 411 is accelerated by interacting with the airfoil, activates the agitator arms 414, and the air exits via the air supply outlet 412 to the ball duct 300 which feed the projectiles 800 a to the projectile launcher 200.

FIG. 8 exemplarily depicts an operation of the hopper 400, the feeder carousel 400 a, and how the projectiles 800 a are provided thereto via the storage (tire 750). As is shown in FIG. 8, the projectiles 800 a are stored on top of the hopper 400 and the agitator arms 414 separate the projectiles from each other. The airflow is provided thereto and the arms rotate counter-clockwise and feed the projectiles 800 a out the air supply outlet in the 412A direction. The projectiles 800 a travel through the ball hose 300 and into the projectile launcher 200 via the feeder tube 211. The projectiles 800 a interface with the flywheel 214 to accelerate and shoot the projectiles 800 a out of the barrel 212.

Thereby, the invention describes above is for a toy projectile launcher assembly 100 installed in a ride-on vehicle having a flap 760, a tire 750 as a storage device, and a steering wheel 770 with an activation switch, the assembly 100 consists of a projectile launcher 200 installed on a lift 200A that lifts the projectile launcher 200 out of the flap 760 of a hood of the ride-on, a hopper 400 having a feeder carousel 400A which feeds projectiles from the tire into an air supply outlet 412 of the hopper 400 to a ball hose 300 which connects from the air supply outlet 412 to the projectile launcher 200 and an air supply inlet having an airfoil, and a blower that provides air to the air supply inlet of the hopper which is sped up when passing the airfoil and entering into the hopper.

In another embodiment, the invention may comprise the projectile launcher 200, a hopper 400 that is connected to the projectile launcher 200 via a ball hose 300, a storage device 750 that provides projectiles 800 a to the hopper 400, and a blower that provides air to the hopper which causes the projectiles 800 a to flow from the storage device 750 to the projectile launcher 200 via the ball hose 300.

The invention can be made modular. That is, the invention can be made as a version that can be worn on a backpack with a detachable gun. This will enable the user to mount the projectile launcher on the front of the vehicle, then easily unclip it and reclip the launcher on their arm to fire without the vehicle base. Think kids move from outdoor to indoor. They have to depart the vehicle but stay in the game. After extensive research, it was found that there was not an easily usable toy that could keep a sustained battle going for children playing in a neighborhood. The constant reloading of products on the market made the games less enjoyable for children. The invention was design for a child such that the child could easily use without too much effort. The desire to ensure an advantage over children in the local neighborhood led the inventive step of developing the invention that could store a larger number of rounds, fire at a high rate, and work with minimal steps.

Although the activation for the projectiles 800 a to be launched was via the steering wheel 770, a similar activation could be via a “trigger” on a conventional toy gun should the assembly 100 be adapted to a different type of assembly not on a ride-on.
